Metabolite Identification
Common NameIsoprenyl alcohol
DescriptionIsoprenyl alcohol, also known as CH2=chc(CH3)2oh or methylbutenol, belongs to the class of organic compounds known as tertiary alcohols. Tertiary alcohols are compounds in which a hydroxy group, -OH, is attached to a saturated carbon atom R3COH (R not H ). Isoprenyl alcohol is an extremely weak basic (essentially neutral) compound (based on its pKa). Isoprenyl alcohol is an earthy, herbal, and oily tasting compound. Outside of the human body, isoprenyl alcohol has been detected, but not quantified in, a few different foods, such as blackcurrants, citrus, and fruits. This could make isoprenyl alcohol a potential biomarker for the consumption of these foods. A tertiary alcohol that is 3-methylbut-1-ene carrying a hydroxy substituent at position 3.
